Cran1, member of a new class of OLD family ATPases, functions in cell cycle progression in an archaeon

EMBO Reports
Overcoming lysogenization defect (OLD) proteins are diverse ATPase-nucleases functioning in antiphage defense in bacteria. However, the role of these proteins in archaea is currently unknown.

Heavily Armed Ancestors: CRISPR Immunity and Applications in Archaea with a Comparative Analysis of CRISPR Types in Sulfolobales

Biomolecules, 2020
Prokaryotes are constantly coping with attacks by viruses in their natural environments and therefore have evolved an impressive array of defense systems.

Nitrogen regulation of protein–protein interactions and transcript levels of GlnK PII regulator and AmtB ammonium transporter homologs in Archaea

, 2013
Gene homologs of GlnK PII regulators and AmtB-type ammonium transporters are often paired on prokaryotic genomes, suggesting these proteins share an ancient functional relationship.

Differential regulation of Ota and Otb, two primary glycine betaine transporters in the methanogenic archaeon Methanosarcina mazei go1 [PDF]

, 2008
Methanogenic archaea accumulate glycine betaine in response to hypersalinity, but the regulation of proteins involved, their mechanism of activation and regulation of the corresponding genes are largely unknown.

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Archaea [PDF]

, 2021
In agreement with their close relationship to eukaryotes, Archaea encode informational processing machineries that closely resemble those of eukaryotic representatives. The composition of archaeal cell membranes differs fundamentally from those of Bacteria and eukaryotes.

Experimental characterization of Cis-acting elements important for translation and transcription in Halophilic Archaea

, 2007
Summary The basal transcription apparatus of archaea is well characterized. However, much less is known about the mechanisms of transcription termination and translation initation.

Chronic alcohol consumption compromises gut barrier integrity and promotes endotoxemia: Implications for sepsis susceptibility in immunocompromised hosts

Animal Models and Experimental Medicine, EarlyView.
Chronic alcohol exposure disrupts intestinal barrier integrity, resulting in a leaky gut and enhanced translocation of lipopolysaccharide (LPS) and microbial products into the systemic circulation. Alcohol‐induced endotoxemia drives exaggerated pro‐inflammatory responses, mitochondrial damage, and activation of the cGAS–STING pathway, particularly in ...

Lipidomic chemotaxonomy aligned with phylogeny of Halobacteria

Frontiers in Microbiology, 2023
Archaea play an important role in global biogeochemical cycles and are considered ancestral to eukaryotes. The unique lipid composition of archaea, characterized by isoprenoid alkyl chains and ether linkage to glycerol-1-phosphate, offers valuable ...
